[1] The variability of stratospheric aerosol loading between 1985 and 2010 is explored with measurements from SAGE II, CALIPSO, GOMOS/ENVISAT, OSIRIS/Odin space-based instruments. We find that, following the 1991 eruption Mount Pinatubo, levels increased by as much two orders magnitude only reached "background levels" 1998 2002. From 2002 onwards, a systematic increase has been reported number investigators. Recently, trend, based on ground-based lidar measurements, tentatively attributed to...
Abstract. The possible impact of deep convective overshooting over land has been explored by six simultaneous soundings water vapour, particles and ozone in the lower stratosphere next to Mesoscale Convective Systems (MCSs) during monsoon season West Africa Niamey, Niger August 2006. vapour measurements were carried out using a fast response FLASH-B Lyman-alpha hygrometer. high vertical resolution observations instrument show presence accumulation enhanced layers between tropopause at 370 K...
Five long‐duration flights with the Mongolfier infrared (MIR) balloon lasting 15 days, on average, have been conducted in Arctic winter stratospheric vortex 1997, 1999, and 2000. Temperatures from European Centre for Medium‐Range Weather Forecasts (ECMWF), Met Office (MO), National Centers Environmental Prediction (NCEP), Data Assimilation (DAO), NCEP/NCAR reanalysis (REA) compared to observations 4 146 hPa. Occasional large errors (>14 K) occur each analysis, mainly above 30 In 2000...
